refactor: Reduce cyclic dependencies in src/

[claremacrae]

Description

Reduce cyclic dependencies between source files, by:

• Moving Priority and TaskRegularExpressions out of Task.ts
• Moving getPrintableSymbol() from StatusRegistryReport.ts to StatusSettingsReport.ts

I decided to version control circular-deps.txt for a while, to keep an eye on any growth of cyclic dependencies. It does have the annoyance that it contains a flickering time measurement, but I'm assuming it's likely only me and @ilandikov who might run it, and we can try and revert any changes if the only difference is from running the tool and getting a differing timing.

The file can be updated with:

yarn run circular-deps-text

And see the similar

yarn run circular-deps-image

Motivation and Context

It's kind of a constant process of trying to simplify code by reducing these dependencies. See #1402 for an earlier attempt.

How has this been tested?
